What characterizes insecure-resistant attachment in children?

Insecure-resistant attachment is characterized by significant distress when the parent leaves, demonstrating a child's reliance on the parent as a secure base. These children often find it challenging to explore their environment independently, as their anxiety causes them to focus more on the potential absence of their caregiver. When the parent returns, children with this attachment style may display mixed emotions, seeking closeness yet also exhibiting signs of anger or frustration. This complex reaction indicates their struggle with feelings of safety and security in the caregiver's presence.

The other choices illustrate attachment styles or behaviors that do not align with the features of insecure-resistant attachment. Children who exhibit great exploratory behavior in the presence of a parent or who are indifferent upon the parent's return display traits associated with secure or avoidant attachment styles, respectively. Insecure-resistant children are specifically defined by their distress and ambivalence towards their caregiver, which is why the correct choice emphasizes their distress upon separation.
